Fuses # 19 and #24 are fed from the same source, one is not tied to the other.
Fuse #30 feeds the ignition coils, radio cap, and the coil on the PCM power relay ( through the PCM diode ).
The normally open contacts on the PCM relay is what Fuse #24 is feeding, as well as engine fuse #1.
Now if my memory ( just having been jogged a bit ) is correct, this is also the same circuit to the heated O2 Sensors.
Might want to check H02S #11 and #12 wiring harness for chaffing. Usually caused by the wire falling against the pipe.
Hope this is it.
